Vagrant version issues

Fixed, issue where Vagrant was issuing warnings.

> There were warnings and/or errors while loading your Vagrantfile.
Your Vagrantfile was written for an earlier version of Vagrant,
and while Vagrant does the best it can to remain backwards

significantly enough to warrant a message. These messages are
shown below.

> Warnings:
* The 'v-root' shared folders have been renamed to 'vagrant-root'.
Assuming you meant 'vagrant-root'...
